Hello, Finally motivated to get an UOA (And my first post!):
2006 Yamaha Roadliner (1,900 air-cooled V-twin "Powercruiser")
Recent use has been very seasonal, This sample was taken after the winter hibernation. Oil only had ~550 miles on it but was ~11months old. Most years I've been changing the oil every 6months +/-. I've almost always used Factory filter and this Yamalube Full-Syn 15w-50 "With Esters!"
If the weather holds out and my work/Army schedule is not too crazy this year, maybe I'll get 2-3k. Think I'll just go the whole year based on this report. What do you think?
